Abstract
Visual cortical prosthesis (VCPs) are currently in development and there has already been some
speculation about which algorithm is best to use in these implants. Semantic segmentation seems
like a obvious choice because the algorithm also gives vision to self-driving cars. However, semantic
segmentation is a slow and complex algorithm that predicts around 200 classes, which are not
necessary when predicting phosphenes. Therefore, semantic segmentation is compared to two simpler
algorithms, edge detection and a proposed neural network that predicts phosphene images from input
images. The results indicated that although being the slowest of the methods, semantic segmentation
makes the best phosphene images. The edge detection and neural network algorithms need some
alterations to be able to make phosphene images that are usable in VCPs.
